JOHN B. GORBELL, OF LA OTTO, INDIANA, ASSIGNOR OF TYVO-THIRDS TO FRANCISA. HOGUE AND XV. JAMES HOGUE, OF SAME PLACE.

HYDRAULIC REGULATOR.

SPECIFICATION forming part of Letters Patent No. 318,722, dated May 26,1885.

Application filed November 20, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN B. GORRELL, a citizen of the United States,residing at La Otto, in the county of Noble and State of Indiana, haveinvented certain new and useful Improvements in Hydraulic Regulators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference beinghadto the accompanying drawing, and to letters and figures of referencemarked thereon, which form a part of this specification.

The figure of the drawing is a sectional view of a well showing mydevice attached.

This invention has relation to hydraulic regulators for windmills, andit consists in the construction and novel arrangement of devices, ashereinafter set forth,and pointed out in the appended claim.

In the accompanying drawings, the letter A represents a windmillforce-pump, and B the wall of the well.

0 indicates the supply-pipe, the end of which is attached to the pump ata. Through this supply-pipe the water passes to the outlet D in the tankZ. The end of this supplypipe is provided with a float-valve, E, whichis designed to close the opening when the tank is full of water,andthereby to produce a backpressure, causing the water to pass into thepipe F and into the cylinder-cap G, where it passes into the cylinderII. In this manner the pressure of the water is brought upon the pistonI, causing it to move downward w1th its stem or red J, to which the wireit is connected.

L is the counterbalance-lever,pivoted at M, and having one of its armsconnected to the upper end of the wire L.

The lever L is provided with the counterbalance-weight N,and isconnected by the opcrating-wire I to the mechanism for throwing thewind-engine out of gear, which mechanism may be of any ordinary orapproved construction. hen the piston I is forced downward, thewindengine is thrown out of gear and held out of gear until the outletof the discharge-pipe is allowed to open by the falling of the float,caused by the removal of water from the tank. In this operation thewater is forced out of the regulating-cylinder by the action of thecounterbalaneing-lever, and the connection P is slackened,taking thestrain off the shifter and allowing the wind-engine to move into gearand proceed with the pumping operation.

The connected end of the counterbalancelever is turned upward, as shownat m,to give the hydraulic pressure more power over it as the pistondescends.

In the construction illustrated the regulat' ing-cylinder is providedwith a band,to which is connected a stirrup, whereby the cylinder isconnected to the supply-pipe.

The cylinder-capG is provided with astuifing-box, Q, at its top end,through which the stem or rod J passes. The object is to prevent theescape of water at top of cap G.

I am aware that it is not new in windmillpumps to provide a tank havinga supply-pipe therein operated by a float, and a counterbalance-leverconnected with the piston of a cylinder, and therefore do not claim suchdevices broadly.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

A hydraulic regulator for windmill-pumps, having a counterbalance-leverformed with an upturned operating-arm and connected to the piston I, theregulating-cylinder H, com1nunicating with the supply-pipe of the pump,and the tank Z, having a float operating the Valve of the outlet of thesupply-pipe in said tank, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. GORRELL.
